[Nexus 5 Q&A, Help & Troubleshooting] tmagritte:
I've got 2 Vu's: one on my nightstand that I use for overnight charging and one at my desk at work.

So far I've never run into this issue with the one at home but the one at work after a few days of working fine has had this issue for the last 3 days. It's not 100% consistent - Yesterday I was able to get it to charge in portrait mode without overheating after previously removing it due to overheating. Later in the day, however it overheated again. Actually, at this point it was already at 100% and stable for over half an hour when the temperature started to go up eventually hitting 45 deg C and triggering the alarm I set in Battery Monitor Widget.

As others have mentioned, when my phone gets to 45 deg C it seems to stop charging (usually around the 80% range) but the temperature remains high.

Also, as others have observed, I've not had this issue occur with the phone in landscape position, although I find it rather awkward as I have to position it just right to get a charge started without having buttons pressed accidentally and waking the phone in this position without picking it up is also awkward - sort of ruining the advantage of this over plugging in a USB cable.

Unlike a previous poster, I have not found tech support to be at all responsive. I sent my first email 2 days ago, then an update yesterday and so far have had no response.

It's a shame as otherwise it's a great charger.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
This makes sense. Also, I guess the Landscape to Portrait trick may have been a fluke for me. Like NCguy said, the light turns off when you flip it, then back on. So it basically resets itself to Portrait mode. In other words, it didn't really work for us.

Yup. Same here. Still waiting to hear back.

I actually think I will be returning my Tylt Vus for a refund. My last day in the return window is tomorrow for the first one. I tried a friend's Nexus 4 Orb charger, and that thing is super nice. Or, I may try the Nokia DT-910 standing charger. It's unfortunate too since I got these Tylts at such a great price, and when they work, they work great. However, I just can't risk it. Especially when their customer support seems to be shaky at best.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I'm not trying to defend them but allow me to engage in a little speculation.

Tylt is obviously a startup and they appeared to work really hard at getting a very unique product to market. Aside from the obvious technical problem they now face, IMO it's otherwise the hands down best Qi charger out there.

It seems to me that this heat problem caught them totally by surprise after much success with all Qi phones prior to the N5. The N5 is a game changer and the technical issues may now possibly threaten to break them.

At first tech support was very response but they are probably freaking out now as they realize the potential magnitude of the problem. I don't see how they could possibly swap out this much product without breaking the bank. Maybe they can pull it off but these guys were just a kickstarter a few months back.

Anyhow I hope for tylt's sake and their customer's sake that they can survive this. For a startup it must be total nightmare.

And maybe I'm not seeing the true picture at all. As I said, just uninformed speculation. I don't claim to officially know anything.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
I agree with you as well. It's always great to see innovation like this, and I like to support small businesses when possible (although I have no idea how "small" they really are). I won't bore you with my subjective opinions, so I'll skip over all that. Bottom line is, they have to know there's a potential problem with the Nexus 5, yet they still have it listed on their "Compatible Devices" list on their website. I'm not saying they should go crazy and pull the charger entirely off their website. But at the same time, they should at least acknowledge the people who contact them with a problem. Even if it were some generic, scripted response, I'd be happy just knowing they know about it and are working on a fix. Granted, they are probably still trying to figure out what to do, at least tell us you're working on it. Then, after it's been rectified, they can decide how to make it right.

As it looks now, most of us are in the dark about what's going to happen. That's why I think I'll be returning mine. I don't want to have to worry about ruining my $450 device every single time I set it down to charge. I'd rather use the N4 Charging Orb or the Nokia DT-910 as a standing charger, since they appear to be more reliable.
[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
my tylt vu is due to arrive at Monday.

I will try it out though I'm concerned leaving it charging unattended.

what temperatures do you guys think are acceptable while charging wirelessly?

is 45 deg C alarmingly high and can damage the phone in the long run?

I will probably set an alarm during testing.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
Well, when my Tylt was charging normally, the temp would be anywhere from 36-39 C. When it was overheating, the temp hit 50 C and it stopped charging, but didn't turn off. I'm assuming the overheating point built into the phone is probably 45 C, but don't quote me on that. All I can tell you is that 50 C was alarmingly hot in my hands when I took it off.

Meanwhile, on my Nokia DT-900 and my friend's N4 Orb, the temp never got hotter than 33 C. It is said that temps are a tad bit higher on teh Tylt, and ,obviously, wireless charging gets warmer than wired. But as long as your phone status isn't "overheating," you're probably fine.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
If you leave off daydream you can probably keep it under 38C.

When it overheats it jumps up to around 56C. I believe you can probably avoid it by avoiding the technique that was described in post #118 by Mr. Sprinkles.
[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
anyone tested if it's any different charging the phone with a case on, in regards to the overheating issues?
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
I actually have the Diztronic Matte Black TPU case on my N5. Haven't really tested it without a case. But from what I gather, it doesn't really make a difference.
[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
to summarize our findings so far;

placing the nexus 5 on the tylt vu in portrait isn't an option due to the risk of overheating it.

placing the phone on the charger in landscape works without mentioned issues.

correct?
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
Well, there are still some people that haven't experienced any overheating at all. And it's not like it's guaranteed to happen. But yes, AFAIK, the incidents that have been reported have all been in portrait (mine included). I haven't heard of any overheating happening when the phone is laying down on its side in landscape.
[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
if the mentioned issues have to do with the coils in the charger, how come we all have such a different experience with the tylt vu?

i'm having a hard time understanding why this issues are so random and not guaranteed to happen. bad quality control?
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
You and me both, buddy... and everybody else...
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
There are 3 Coils and a IC charge controller sometimes the controller gets missed out or out of its own mind and activates the 3 coils instead of the 1 coil its supposed to activate. you can test this even further with a Kill-O-Watt plug meter and see the draw coming from the Tylt
[Nexus 5 Q&A, Help & Troubleshooting] just4ivaylo:
Using both a Tylt Vu and a Nokia DT-900 with my Nexus 5. Haven't noticed overheating issues.

My N5 is currently sitting on the Vu and it has a case on it plus a credit card pouch with three cards. Still charges and does not overheat.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
For those of you asking why this is so random and why some haven't had the problem -

READ POST 118. PLEASE PUT A LINK TO 118 IN THE OP.

If you want to witness your device overheating simply dock it in the cradle the way its described in the post. IT WILL HAPPEN. Say you don't ever dock it like that? Try docking it a few hundred or thousand times. Eventually you will inadvertently do it. Possibly not if you pay attention every time now that you know what can cause it.

Can other things cause it? Possibly so, but dock it as described and it happens every time.

Please don't say yours doesn't overheat. They are ALL capable of overheating until this is fixed.

TYLT solution thanks Mr. Sprinkles

See post 118

Hey guys, I got this same issue with two TYLT chargers and two different Nexus 5's. I have read about a short term solution that so far seems to work.

Cause of overheating:

1. When the phone is placed against the charger, but 3/4" or so above the chargers bottom plate - this can activate the top charging coil.

2. The phone is then slide down the charger until it contacts the bottom plate. The keeps the top coil active and begins heating the metal (magnetic) circles in the back of the phone.

Solution:

1. Place the bottom of the phone directly onto the bottom of the charger without sliding it down the charger stand. You can do this by angling the top of the phone away from the charger, kinda of like butt first approach. This will keep the top coil from activating and all is well.

Best of luck
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
yes, I was thinking the same thing and will try to be as conscious as I can to do it exactly this way. It's going to be a bit inconvenient because I often dock to my nightstand by feel in total darkness. But its better to go out of your way to adopt this behavior at least until (hopefully) a permanent fix becomes available.

Nexus 5 overheating on Tylt Vu

My Nexus 5 has overheated twice while charging on the Vu. The phone shuts down and the charge is not completed.I won't be using it again.
[Nexus 5 Q&A, Help & Troubleshooting] Mr. Sprinkles:
Guys, that post was in no way intended to be a solution to the problem. I was simply confirming my theory that the upper coil can heat the phone if for some reason most of the energy is directed to it. I'm fairly certain being careful about how you place your phone in the tylt is NOT going to prevent it from overheating. I think the problem with the tylt and the N5 is firmware related.

I'd say the best way to ensure it doesn't overheat is to charge in the landscape position. No one has reported their phone overheating in this position, which makes sense because it should be pretty obvious to the tylt where the qi receiver actually is.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
It may not be the only cause but it is now a verified trigger. Landscape is probably the safest but I'm convinced that your post was likely the cause of my incidents.
[Nexus 5 Q&A, Help & Troubleshooting] Mr. Sprinkles:
My solution to the button pressing problem was to stick a couple rubber bumpers on the ledge. They're away from the back just enough to miss the buttons while still supporting the phone. Works and doesn't look too bad. Thinner bumpers would look better, but these are what I had on hand.

Of course, the ultimate solution would be for tylt to fix the heat problem... but this works ok in the meantime!
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
At this point I'm really curious to see if anyone experiences overheating going forward that docs in landscape according to the suggestions in 118.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
I actually just pulled the trigger and sent mine back for a refund. I ended up ordering the N4 Orb on Amazon. I really wanted to keep my Tylts, but I just couldn't risk it. The lack of customer response to TWO emails wasn't very reassuring either (although they did respond to my refund request rather quickly). I always charge my phone in portrait orientation, so having to charge it in landscape just to make sure it works properly would just be plain annoying. You shouldn't have to take precautions like that on something that is supposedly compatible with your device. I wish you all luck, and really hope Tylt can make it right for all of you.
[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
anyone tested if it's any different charging the phone with a custom kernel flashed, in regards to the overheating issues?

Nexus 5 & Tapatalk.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I don't blame you at all and wish you the best with the N4 Orb. I don't like landscape at all either and I'm hoping that while Mr Sprinkles says not to bank on it that by observing his no-slide technique just maybe I can avoid further overheats until a possible fix is made available. Maybe unrealistic but that's my hope at this point.

Again good luck and enjoy that N5!

Overheating Issues

I just bought two of these over the holiday, one for myself and another for a friend and I just experienced a overheating issue, luckily i caught it before it got too hot. Plus I'm over protective with my toys so i usually run my chargers on a timer so they will only charge for a few hours before shutting off. After this incident I searched and found this thread but now I'm wondering if i should return the chargers?

I've since installed an app that tracks the battery temp and will alarm when it goes above a certain temp and also have been charging in landscape. So far after about 6 charge cycles the battery temps have remained under 30 to 32 C while charging, i turned on daydream with DashClock widget and saw the temps jump to 36 C and climbing so i decided to turn it off.

I really love this charger and i will probably keep it but i'm more worried about the one i sent to my friend in Toronto, my ocd kinda keeps me constantly monitoring my phone but I'm worried my friend will leave his charging overnight and fry his N5.

I also emailed CS a week ago but haven't received a response either so i'm hoping they will respond and have a fix soon.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
This is why I returned both of mine for refunds. Just make sure to tell your friend to charge in landscape orientation. I mean, it's not really a 100% guaranteed to not happen again, but it makes sense why it would work.
[Nexus 5 Q&A, Help & Troubleshooting] R2canoe:
Yeah, just sucks that this is an issue since i've been wanting to get one since the Kickstarter campaign. It works great with my N7 and the temp will stay below 25 C even with daydream on.

My friend likes to keep his N5 on the charger since he's constantly using it for work and traveling, so would suck if he needed his phone and it didn't charge and overheated.

Hopefully they'll come up with a fix soon and we wont have to worry about it anymore.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
Yeah. I just hope when they do come up with a fix, they let people know (at least the ones that have reached out to them) they fixed it and what they are going to do. As others have said, I would imagine it would be a HUGE hit if they reached out to EVERYONE who bought one with a recall or something. So if I were you (or any of the others here that still have the charger), I would stay on them to make sure they know their customers know there's a problem.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
good advice
[Nexus 5 Q&A, Help & Troubleshooting] R2canoe:
I almost think they would have to just say it was not compatible with the Nexus 5 because replacing every charger would put them out of business and just refund/replace the ones that write in and complain about it not working with their N5 with a 2.0 model that they release.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
It gets a bit tricky though if there's even the slightest risk of fire. I'm not saying there is that risk but then again I don't know what happens if you leave it on there long enough. I will say the thought has crossed my mind as a product owner.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
Yeah. That's what irritates me about this whole thing. The fact they still have it on their compatibility list is pretty shady. At least put an asterisk with a footnote or something saying they are still in the process of testing compatibility or something. I highly doubt they would not want to advertise the fact that the 1st model had issues, when/if they come up with a fix (like putting it in their website) . I just hope they handle it properly. It would be shady if they fixed it on the down low and never admitted there was an issue with the 1st revision. I don't want to be a drama queen or anything, but I can see this issue as a possible fire hazard as well. Don't want to leave my family's safety up to the chance that my phone renders itself safe from catching fire or exploding.
[Nexus 5 Q&A, Help & Troubleshooting] mabru2001:
Got word back from them in like 3 hours. IDK why they were not responding to everyone else. So their fix is that we have to be careful how we charge on their charger... Kinda kills the whole throw it down and go about your day convenience.
[Nexus 5 Q&A, Help & Troubleshooting] tmagritte:
I still haven't received any response for them. But this response is disappointing. I've tried that approach and it did not work for me. Which means it either isn't a universal workaround or it's quite fiddly about how exactly you place it. Even if the fix worked as described it's inconvenient and easy to do wrong which means the danger or overheating is still there.

For now I've just been using it in landscape mode which does seem to fix the issue but is less than ideal.

I wonder how hard it would be to open it up and physically disable the third coil?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
If that's the final word then it just plain sucks IMO. I'm not convinced that it is. Everyone is experiencing different support response times and different responses. I wouldn't be surprised if they come up with a fix but are selective about who gets it. Many have been told that a fix is coming, including myself.

It's hard to imagine that they would continue selling the product as is. We all know that it would be courting a disaster.
[Nexus 5 Q&A, Help & Troubleshooting] charesa39:
Wow... Reading that makes me glad I returned mine for a refund. That's just ridiculous.
[Nexus 5 Q&A, Help & Troubleshooting] AliLaPointe:
Just to add my 2 cents, I should be receiving the charger early next week. I contacted them about the concerns of over heating, and they simply said that if it caused issues that I can return it. When asked specifically about the fix being in the works, they stated that they did not have an eta for the fix.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I think this is a critical event for the future of this company and so far I'm not convinced that they are handling it a manner that will ensure their viability.
[Nexus 5 Q&A, Help & Troubleshooting] Mr. Sprinkles:
Hang on, so NCguy was right? Am I understanding it correct? They want you to put the bottom on the ledge first, screen angled towards the floor, then tilt it backwards into place? It's almost as if they just read the last few posts of this thread and said "Meh, that seems like a good fix".

If this really is the problem and it's not a firmware bug, then I think it's picking a coil too damn fast. Give people a chance to lay their phone down first.

And the fact still remains that foreign object detection sucks. This would be much less of an issue if FOD actually worked. It's supposed to throw an error if say, the receiving coil is in the wrong position and it's just heating metal. If it worked, the worst that would happen is we'd come back to a phone that isn't charged and a red light. It would be annoying, but at least your house isn't on fire.

Their solution doesn't amuse me...

---------- Post added at 03:35 PM ---------- Previous post was at 03:26 PM ----------

Wouldn't be hard, the wires that need to be clipped are obvious. But I'm not sure how the controller chip would handle it, might not like it too much. Would be easy enough to solder them back into place if it didn't work though. I might try it...
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I'm not surprised. When tylt told me they were unable to reproduce the problem I sent them your exact instructions to overheat using the slide method. Make sense now?
[Nexus 5 Q&A, Help & Troubleshooting] Mr. Sprinkles:
So they had no clue what was happening until you sent them that? Doesn't inspire confidence...

Well, you've been using this method longer than anyone, does it actually work? Has your phone overheated yet?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I'm not sure if they had no clue or they realized that someone could reproduce on demand so they had to at least officially tell people not to charge according to a now publically known method of overheating.

Mine overheated twice in about 4 months before you made me aware of the slide issue. I tried the slide right after you posted it and it overheated on 1st attempt. Now that I am focused on avoiding the slide it hasn't overheated again but way to soon to say that this is the only problem.

[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
just made my first attempt charging my Nexus 5 on the Tylt VÜ with the mentioned fix in this thread.

phone in portrait / daydream on / dbrand backskin and a Supcase TPU case on

phone reached 45 degrees C in a matter of 15-20 minutes and overheated.

will give the phone some time to cool off and then try charging with daydream disabled.

not a good start...
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
With my experience with the tylt and N5 there are two separate problems. I'll go ahead and give each a name for discussion purposes:

1. Hot Charge

2. Overheat

Hot charge is when the phone gets hotter than you would prefer but never "overheats" or stops charging. It seems like 45C /113 F is about the max temp for that condition. Turning off daydream lowers the battery temp down to about 37C / 99F. The case on/off makes little difference.

Overheat is when the battery temp quickly rises to about 55.5 C / 132 F, and stops charging. The phone reports an overheat condition. The battery seems to remain at that temp until you pull the phone off the charger. The battery may continue to get hotter as I've not ever chosen to test that theory. Daydream may make it worse but it isn't the primary cause of a true overheat and phone settings, software, case etc won't prevent it. The only thing we know for certain at this point that triggers an overheat type charge is the "slide" method of docking the N5 in the charger.

Sounds to me like you probably experienced #1 above. After 15 minutes the phone would have probably been hotter than 45C if was going to "overheat" but it's possible that it was on its way. Anyhow I'm guessing you had #1 and turning off daydream should get you to around 37C next time.
[Nexus 5 Q&A, Help & Troubleshooting] Mythos123:
I used the term "overheat" because that's what DashClock Battery Extension and Battery Monitor Widget reported when the battery temp reached 45 C. Not sure what would have happened if I continued charging the phone, I'm not willing to risk or take any chances...

is this the same thing as "the phone reporting an overheat condition" like you mentioned?

What's your limit in comfortability, in regards to the battery temp?

Anyhow, I'm going to try charging the phone with daydream turned off and report back.
